"It's nice to see that thanks to Edward Mayer's noble endeavours in revising the English texts, without even mentioning your own hard work, the web-site designer's' goodwill, and Igor Fefelov's as well as my own efforts, some Russian-language information will see the world. Thank you very much indeed for tearing down this linguistic Berlin wall."

"How similar the Common Swift nestlings are to Chimney Swifts (a swift is a swift...)! However, there are some distinct differences. In Chimney Swifts, the feathers around the face are the last to develop -- leaving a "frosty-faced" appearance. Also, the primaries of Chimney Swifts apparently stay in sheath much longer than those of Apus apus.

Thank you very much for the great developmental photo sequence -- you made our day in these swiftless months!"

"In my childhood I had to go to the library to check about this name but now I had just to type it in google. I also learned about this bird especially from the wonderful website of Ulrich Tigges from Berlin, a Swift fan, who worked hard to translate the site to 11 languages, including Hebrew, and the more I read the more I realize how much the big things can be hidden from your eyes."

"I am extremely impressed by your amazing website on the Common Swift. I have been running a Swift Conservation Project for the Sussex Ornithological Society in Southern England for several years, and also promoting Swift conservation through my work as a local authority (County Council) ecologist. 
I have gleaned a lot of very useful information from your website. It is great to learn what is happening in other countries."

"We have read some chapters with interest, we can agree with the hand rearing instructions totally!
We have been rescuing hundreds of swifts (apus apus and apus pallidus) for years and we find really satisfactory to feed and free them!"
